Apply a Gaussian blur effect to a 2D element

[LaVache]

hello everyone, wanted to know if anyone had a method to apply a gausian blur effect on a 2D element like a rect or a circle or any other shape, I looked around to see if there had a way to do this in openGL but i couldn't find anything and i'm not very good at openGL, i only know the basics. if you don't see what i want to do i put a picture and basically i want to do like this any shape on minecraft




ah noted I have already tried to import an image it works but it is not suitable for all sizes and I can not create 50 images for each shape
it takes up too much space in my client and it's not great for xd optimization

for a blur the existing blur method, which exists since 1.8.8 including the blur shader, should be sufficient.

pour un flou, la méthode de flou existante, qui existe depuis la 1.8.8, y compris le shader de flou, devrait être suffisante.

it's not really the help that I expected but I will manage, thank

from an earlier thread i noticed that the "Jello Source Leak" contains a method that makes rects blur directly. You could for example just copy paste them.

except i need to do this for any roundRect circle rect triangle shapes
I already use blur but not for such complex forms glScissor does not allow me to do that

First of all u need to do an custom Fragment Gaussian Shader then u gonna draw the whole Minecraft Framebuffer and apply first Horizontally the Gaussian Shader into it and then u apply on the Horizontally Blurred Minecraft Buffer to an Vertical FrameBuffer which u also gonna blur then u bind the Minecraft buffer and draw the horizontal buffer aswell as the vertical buffer where u gonna stencil all Components out which is drawn into an Framebuffer.

OK but can I use this for all types of forms?

yes would look like this then
